Each default connector virtual service has a default policy, which logs the requests/responses and their payloads to a database. You cannot modify the default connector virtual services or their policies. However, you can create additional connector virtual services with custom policies.

If you create a connector virtual service with a custom policy, you can include the actions from the "Monitoring" and "Additional" categories (except for "Validate Schema"); the "WS-SecurityPolicy 1.2" actions are not needed. For example, you might want to create a custom policy that monitors run-time performance, customizes how the service invocations are logged, or optimizes server traffic.
